CONCENTRATOR.

To all whom it may concern:

Be it known that I, HANOEY L. BLACK, a citizen of the United States, residing at Central, in the county of Grant and Territory of New Mexico, have invented certain new and useful Improvements in Concentrators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in centrifugal concentrators and has for its object to provide a very simple device of this character whereby the gangue, tailings and other residual products may be separated from the ore by the centrifugal force of a revoluble disk upon which the ore is deposited.

Another object is to provide means whereby the body of ore may be vertically vibrated upon said disk during each revolution thereof to more thoroughly separate the precious metals from the minor earth products.

A further object resides in the provision of a revoluble disk mounted upon the upper end of a vertically positioned shaft, said shaft and disk being disposed within a funnel, the body of said disk having a downward slope from its center and an angularly extending circumscribing flange portion formed with a plurality of concentric ribs providing riflies thereon behind which the particles of ore are adapted to lodge and be confined, while the baser materials are thrown beyond the periphery of said disk and deposited in the funnel from which they are carried off by a suitable discharge pipe connected to the lower end thereof.

A still further object is to provide an ore concentrator which will be highly efficient in its operation, is durably constructed and which requires but a small amount of power.

With these and other objects in View, the invention consists of the novel construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical section through an ore concentrator embodying my improvements; Fig. 2 is a top plan view thereof Fig. 3 is an enlarged section taken on the line 3 3 of Fig. l; Fig. 1 is a section taken on the line 4,-4. of Fig. 1; and Fig. 5 is a detail perspective view of one of the agitating collars.

Serial No. 527,895.

Referring to the drawing 5 indicates a conical funnel which may be supported in any desired manner or as shown in the drawings by means of the horizontal parallel I-beams 6 which extend entirely through the funnel and support therein the Vertical shaft 7. The lower end of the shaft 7 is rotatably disposed in a circular enlargement 8 integrally formed with the lower beam 6. The upper beam is also provided with a circular sleeve portion 9 through which the shaft 7 extends. lVithin this sleeve portion a friction bushing 10 of Babbitt metal is secured.

A circular disk 1l is keyed upon the upper end of the shaft 7 as shown at 7 and has vertical movement thereon the purpose of which will hereinafter appear, and as shown in Fig. 1 is inclined downwardly from its center at an obtuse angle to its longitudinal center. At the edge of this sloping body portion of the disk, the same is extended outwardly and upwardly at an angle of substantially 15o to form a circumscribing flange 12 which terminates on approximately the same plane with the center of said disk. The inclined body is thickened toward its center as shown at 13 and has integrally formed therewith a central hub portion 14 which is adapted to rovide a bearing for the shaft 7. This hub portion is connected to the inclined disk by means of a plurality of radial spokes 15 which are integrally formed with the disk and hub. Loosely dis posed upon the shaft 7 and secured to the upper I-beam 6 there is a collar 16, and

keyed on the shaft above this collar there is a similar collar 17. The opposed faces of these collars are serrated to provide a plurality of V-shaped ribs 16 and 17 respectively, which radiate from the periphery of the shaft. As will be seen from reference to Fig. 4 there are four of these ribs upon each of the collars which have interlocking engagement with each other. As the collar 16 remains stationary while the collar 17 revolves with the shaft 7 it will be obvious that as the inclined` surfaces of the ribs engage and move upon each other, the collar 17 will be raised upon the shaft 7 which will likewise raise and lower the disk 11. There will be four of such vertical vibrations of the disk during each and every revolution of the same, although it will of course be obvious that by providing a greater number of ribs upon the collars, the vibratory movement of the disk may be increased or viceversa. The collar 16 is also provided witha sleeve or bushing 1-8-inits-bore with which the shaft has frictional engagement.

To insure the separation of every particle? of the precious metal from the various residual deposits, I provide.- al. plurality of con` centric ribs 19 which are preferably formed integral with the disk. It' willb'enoted'that one of these ribs is disposed at the outer extremity ofthe lia-nge 12whi'ch i'sadapted to catch; and retain. withinf theJ disk' the veryf finest particles o'f-'m'etal`r which mig-ht'4 othe`r-r wise be carriedi beyond theperiphery: of the disk by thecentrif-ii'gall force thereof. The' inner inclinedsurface of the flange 12 is gradually mergedl into-the sleped perticn ofE the body off the disk, as* sh'ownati 20-t where the thickness" ofi the disk is--increasedt and itsA upper surface gradually' curvedint-o` the' two oppositely' inclined surfaces. -ny suitabledriving means maybe employed for operat-i` ing the shaft tfo-rotat'el said'i disk. @ne ofsuchmea-ns isshown in tli'e dra-wing' and comprises a laterallyextending drive sha-ft whichL isL supportedf from the` funnel 5v by meansl of the` hanger 2217 Uponthis shaft" a band-'wheel or pulley 23' is-secure'd tow-hich the" power' is applied` from any suitable source offsupply. The interior portion of the shaft 251i is* disposed within the sleeve 24 which`L is* secured at' oneend toz the funnelv body. Upon5 theinner end of the shaft abevel gear 25 is secured and meshes with= asimilar gear-26l carried bythe sha-ft 71 The uppercircumscribing edge-ofthez funnel 5-isvertically extended asshown:- at 27, such ver'- tical portion projecting above-the pl'ajne ofl the disk 11f and adapted Co-preventthe light-er materialsf-rom escaping over the sides of the' funneli but depositing tliem wit-hinthe same exteriorly ofthe disk. c

Upon reference to- Fig; 3 it will be seeir tha-t each of the supporting I-beams (itis-pro vided withE anupper flange 28' of substantiall'y ifi-shapedv cross sectional fer-nr, wliereby the gangue and tailingswhichhave been separatedr from the o're during the concentrating process is prevented from lbdging uponthe Ilbeamsi These base materials gravitate downwardly within the funnel? andare carL riedf off' b'y a= discharge p pe 29" suitably secured to thelower end thereof.

In the operationl of the' device, the minedore is depositedi upon thecenter of" the diskin large quantities-, andgravita-tes down-- wardly and outwardly tow-ard: the flange 19j. Asthe disk is` revolved, it will beV moved vertically up andE down upon theshaft 75 by the engagement of the serrated faces ofthe* collarsv 16 and 17I asf previously described; lhis-movement of thedisk will' vibratex thel ore and tend tov settle the heavier metalswhich' it is desiredto separate from thel various baser products usuallyfound in the-A crude materia-l Owing tothe centrifugal i for-ce ofthe disk, these heavy particles of meta-lwillv becaught behindi the riffles 19 and prevented from flying beyond the periph- 'eny oi' the disk. The lighter particles or tail-ings will, however, be thrown from the disk and. subsequently discharged fronithe yfunnel by this centrifugal force. It will be obviou'sthat as the flange 12 is inclined with Vrelation to the body of thedisk, that the outward flow of thel materialy over the riffles 1'9 would-- be* retarded by said rillieswereit not for theprovision oftheconically' formed central body portion of the disk. It is by thispeculiar construction" that the proper operation of t'hefmachine-is attained;Y Vhen the ore is deposited upon the centerl of' the' revolving"` disk, ity will quickly gravitate downwardly and outwardly therefromi onto theupwardl-y inclined circumscribing riffled flange, and as the point ofl juncture of the conical body portion and the flange is con'- caved, as' at 20, and forms a perfectly smoothl unbrokenl surface between the two' portions` of the revolving, disk, the movement of the material onto the flange will not be intercepted or retarded toY any appreciable extent, and it will strike' the first ofthe concentrierililes with the accumulated lloc ficient to separate the ore, andi by forming Y saiddisk w-iththe comparatively steep' in- 'n clinedz body, the angular circumscrlibing flange may bei'ncreased in width so as to perf mit of' the provision of a' number-of the' riffles thereon without in'ip'airing' the efficiency' of thel separator or overcomingt'lie desired result of the centrifugal action; In' this manner everyv particle'of` the` precious metal may be saved while the baserminerals are' completely separated therefrom and'v carried out. rPhe outer circular riliie1'9 on the'disk fla-ngeI ,1'2" will cat-'ch and retainY the most minute particles of metal which" are often lostd andi carried' offr with what'L is known asV mineral black'sandin` the ordinary process of" washing" the' ore. Thus al considerable'` savL ing' isattained while' the-,desired result' is very speedily accomplished. Y

From the foregoing it will be seen that I? have provided a centrifugalVV ore concentratorv which while* ofcomparatively 4simplel construction' is admirably designed forti-ieA pur-poseV in view, requiring a 'minimun'r amount ofI power for itsV operation'. The: various part-sl are eas-ily manufactured and the; whole device may be" assembled-y and prolduced at a very moderate expenditure. The* capacity of the disk would preferably be about two tons although itis to be understood that this capacity may be greatly increased with a proportional increase in the proportions of the respective operative elements.

Numerous other minor modifications may be resorted to within the scope of the claims without departino from the s iritl or sacrificing any of the advantages of the invention.

Having thus described the invention, what is claimed is:
